The Clever Coin Trick

A borrowed 20p coin is placed on the small pedestal. The pedestal is now covered. When the cover is lifted, the coin has simply vanished. Picking up the base a rattling noise is heard inside. The spectator thinks it's the coin. When the base is opened, a small disc drops out giving a message on it you have written earlier. For example: 'Thanks for the coin!!' Or it could be a card value or any other message
